Weird Brown Blotches?

I’ve recently noticed that Kasper has some blotches starting to appear on his cere. They are a sort of brown color, so I’m hoping that it isn’t anything too serious. I had some advice from Avian Avenue here to call a vet just in case, so I’ll be trying to get a hold of one as soon as possible. I wonder what it is? I thought it was a liver problem at first, but…

The brown spots look like they are growing as part of his skin, and I don’t think that is a good sign. I’m praying that this won’t turn out to be a serious problem, but I may be being too paranoid, you never know though!
